Buy Aluminum extrusion

Which are the best and biggest seller? Is there any different colour? Painted for example?

Biggest and best may not be the same. It will also depend on which continent you're closest to. There are lots of different colors available from the manufacturers. You can also have them anodized or powder coated in any color. Paint usually doesn't work very well without a thorough preparation because aluminum oxidizes very fast and paint doesn't stick well to the oxide.

You should go to each manufacturer and check their specifications to meet your needs. Tolerance for straightness, length, width, etc. should all be taken into account.

Or you could just buy from Misumi

Thanks for your reply... maybe there are also different colors on anodizing as well... i will check ... you suggested me to check each manufacturer.. is there any list of them somewhere?

I have had good results from www.8020.net. Fast service and reasonable prices.,but as stated above it depends on where you are located

I've seen the website and seems great... Unfortunately I'm quite far from Indiana... I'm based in Italy so maybe there is something similar in Europe? Maybe Misumi and 8020 could both ship in Europe but I think should be easier and cheaper some thing directly in Europe... Ahhhh otherwise I could move in USA .. Should be a not bad idea!

Try Motedis, that's who I bought my extrusions from.
